What is ETH: A Comprehensive Guide to Ethereum's Native Cryptocurrency

Ethereum's Positioning and Significance

In 2015, Vitalik Buterin and co-founders launched Ethereum (ETH), aiming to address the limitations of existing blockchain platforms by introducing programmable smart contracts.

As the first major smart contract platform, Ethereum plays a crucial role in DeFi, NFTs, and decentralized applications (dApps).

As of 2025, Ethereum has become the second-largest cryptocurrency by market capitalization, boasting over 413 million unique addresses and a thriving developer ecosystem. This article will delve into its technical architecture, market performance, and future potential.

Origins and Development History

Birth Background

Ethereum was created by Vitalik Buterin and co-founders in 2015, with the goal of expanding blockchain technology beyond simple value transfer to support complex, programmable applications.

It emerged during the early blockchain boom, aiming to provide a platform for decentralized applications and smart contracts, opening up new possibilities for developers and users across various industries.

Important Milestones

• 2015: Mainnet launch, introducing smart contract functionality to blockchain technology.
• 2022: The Merge upgrade transitioned Ethereum from Proof-of-Work to Proof-of-Stake, significantly reducing energy consumption.
• 2023: Shanghai upgrade enabled staking withdrawals, enhancing liquidity for ETH stakers.
• 2025: Ecosystem explosion, with thousands of dApps and DeFi protocols built on Ethereum.

With support from the Ethereum Foundation and a global community of developers, Ethereum continues to optimize its technology, security, and real-world applications.

How Does Ethereum Work?

No Central Control

Ethereum operates on a decentralized network of computers (nodes) worldwide, free from control by banks or governments. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.

Blockchain Core

Ethereum's blockchain is a public, immutable digital ledger recording every transaction. Transactions are grouped into blocks, linked through cryptographic hashes to form a secure chain. Anyone can view the records, establishing trust without intermediaries. Layer 2 solutions and upcoming sharding technology further enhance performance.

Ensuring Fairness

Ethereum uses Proof-of-Stake (PoS) consensus to validate transactions and prevent fraudulent activities like double-spending. Validators stake ETH to maintain network security and receive ETH rewards. This innovative approach is significantly more energy-efficient than the previous Proof-of-Work system.

Secure Transactions

Ethereum uses public-private key cryptography to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security while transactions remain pseudonymous. Additional features like smart contract audits and formal verification enhance security for decentralized applications built on Ethereum.

Ethereum's Market Performance

Circulation Overview

As of September 9, 2025, Ethereum's circulating supply is 120,705,000.4650543 coins, which is also its total supply. The maximum supply is infinite, indicating an inflationary model.
New coins enter the market through mining and staking rewards, influencing its supply and demand dynamics.

Price Fluctuations

Ethereum reached its all-time high of $4,946.05 on August 25, 2025, driven by increased institutional adoption and the successful implementation of network upgrades.
Its lowest price was $0.432979, occurring on October 20, 2015, during the early stages of the project's development.
These fluctuations reflect market sentiment, adoption trends, and external factors affecting the cryptocurrency space.
